Dongfeng KR trcuk parts electronic throttle Accelerator pedal assembly 1108010-C5102

At the core of the assembly is a dual-channel hall-effect throttle position sensor (TPS) that delivers ultra-precise electronic control. With a resolution of 0.05°, it translates pedal rotation (0–36° range) into real-time digital signals (0.5V–4.5V output) to the ECU, enabling linear, lag-free acceleration—reducing throttle response time by 40% compared to mechanical throttle systems. The dual-channel design provides redundant signals (primary and backup), ensuring the ECU receives accurate commands even if one channel fails, and supports Dongfeng KR’s engine torque management functions (e.g., cruise control, load-based power adjustment). Unlike low-resolution sensors that cause jerky acceleration, this electronic control ensures smooth power delivery at all speeds (20–100km/h), critical for heavy-haul or urban delivery scenarios

Built to withstand the harsh conditions of commercial trucking—constant vibration, temperature extremes, and moisture—the assembly uses high-performance materials. The pedal arm is crafted from 3.2mm-thick cold-rolled steel (Q345B grade) with a corrosion-resistant electrophoretic coating, enduring 600N of pressure (well above average foot force) without bending. The pedal pad is made of oil-resistant EPDM rubber (75 Shore A hardness) with a diamond-pattern texture, ensuring non-slip grip even with greasy work boots. The electronic sensor module is sealed to IP6K9K standards (dust-tight and high-pressure water-resistant), protecting internal circuits from road spray, dust, and humidity. The pivot joint uses a self-lubricating stainless steel bushing (304 grade), enabling 1.2 million+ pedal cycles (equivalent to 6 years of heavy use) without squeaking or seizing

Engineered with safety as a top priority, the assembly integrates comprehensive safeguards for electronic throttle systems. It includes an over-travel limit stop (preventing pedal rotation beyond 36° to avoid TPS damage), a voltage surge protector (clamping at 28V to shield the sensor from electrical spikes), and a thermal shutdown function (activating at 70°C to prevent overheating). The dual-channel TPS features cross-check logic: the ECU compares both signals, and if a discrepancy exceeds 5%, it triggers a limp-home mode (limiting engine power to 50%) for safe vehicle operation. Additionally, the electronic connector has a locking tab to prevent accidental disconnection, and the sensor module is flame-retardant (UL94 V-0 rating) to reduce fire risk. These features meet ISO 26262 functional safety standards, eliminating risks of unintended acceleration

Designed for hassle-free replacement by fleet technicians or DIY owners, the assembly simplifies setup with plug-and-play functionality. It includes all hardware: 4 OEM-spec M6×22mm stainless steel bolts, lock washers, and a vibration-damping foam gasket that reduces pedal noise. Installation takes 20–25 minutes: align the assembly with the cab’s mounting holes, tighten bolts to 28 N·m torque, and plug the 8-pin connector into the ECU harness. Unlike aftermarket electronic pedals that require manual calibration via diagnostic tools, this unit is pre-calibrated at the factory—the ECU automatically recognizes the pedal and syncs with the throttle body within 30 seconds of ignition. For maintenance, the rubber pad is removable (via hidden clips) for cleaning, and the sensor module requires no periodic servicing. Each unit undergoes TPS signal accuracy testing, vibration trials (15G acceleration, 10–2,000 Hz), and environmental resistance checks, backed by a 24-month warranty against defects (e.g., sensor failure, connector damage, pedal arm deformation)
